A dome of high pressure building over the western half of the country has returned Phoenix to a hot and humid pattern typical of July, with temperatures forecast to exceed 110 degrees Fahrenheit, FOX 10 meteorologist Krystal Ortiz reported Monday.
The National Weather Service Phoenix office has issued an Extreme Heat Warning for Tuesday, July 7 through Thursday, July 9. The agency forecasts highs of 112 to 116 degrees Fahrenheit across the Phoenix metro, with overnight lows holding in the 80s to 90 degrees Fahrenheit, limiting any meaningful cooling between peak heat days.
High pressure will build over the region this week, the NWS said, allowing temperatures to climb well above normal and producing widespread Moderate HeatRisk with areas of Major HeatRisk during the midweek period.
Scottsdale conditions will be somewhat moderated: FOX Weather's local forecast shows partly cloudy skies with highs of 103 to 107 degrees Fahrenheit and lows in the upper 80s.
The heat pattern is consistent with prior weeks. A previous FOX 10 forecast noted that below-average temperatures from the Independence Day weekend would end as a large ridge of high pressure moved in from the east, and AccuWeather separately confirmed the Southwest is bracing for highs reaching 110 degrees in Phoenix and Palm Springs.
